Gypsum - an overview | ScienceDirect Topics
Gypsum source, application rate, and particle size all have their effect on crust formation and IR (Figure 2).Although the IR for soil without gypsum decreases sharply as the cumulative rainfall increases, the IR remains relatively high in the presence of phosphogypsum (PG), whereas the effectiveness of mined gypsum (MG) on IR is significantly less.

Gypsum - Chemical Formula, Properties, Types, Uses and FAQ
Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
